texindex – Simple indexing using standard Unix commands

Start­ing from LaTeX\in­dex com­mands, and
makeidx.sty from the LaTeX dis­tri­bu­tion, this set of
sim­ple scripts (us­ing sed, sort, awk
and uniq) gen­er­ates an in­dex file to be used in a
\printin­dex com­mand.

This util­ity is not to be con­fused with the com­piled pro­gram of
the same name, which is part of the
tex­info dis­tri­bu­tion.
